Hint: The head of the sperm contains the densely coiled chromatin fibers which are surrounded by an organism that contains enzymes used for penetrating the female egg. Its flagella-like end part contains a set of microtubules.
Complete step by step answer:
Sperm is a male gamete that is responsible for fertilization of the egg. The semen which is present in the sperm gets thickens and helps the sperm to stay as near to the cervix it can. It has a long and flexible tail which is the flagella which helps in swimming. The process during which sperm cells are formed is known as spermatogenesis and it takes place in the seminiferous tubule of the testis. The lifespan of sperm cells is very short.
Its head contains the nucleus and chromatin fibers. The penetration of sperm into the egg is because of the presence of acrosome in the head. Man releases many millions of sperm cells during ejaculation which start swimming towards the fallopian tubes as they have to proceed further to meet and fertilize the egg. The sperm in the female genetic tract can live up to 48 to 72 hours.
Millions of the sperms are released but only the strongest one makes its way into the egg and produces a zygote after fertilization. Fertilization takes place in the fallopian tube. Once the egg is fertilized, the egg moves towards the nucleus.
So, the correct answer is, ‘A nucleus, an acrosome, a pair of centrioles and a tail’.
Note: The term sperm is derived from the Greek word ‘Sperma’ which means seed. The sperm cells also contain semen in which there are certain elements present that protect the sperm cells in the female genital tract until they reach up to the egg.
